OID-BURNER.

SPECIFICATION forming part of v Letters Patent N o. 725,176, dated April 14, 1903. Application led august 16, 1902. Serial No. 119,945. (No model.)

To all whom t may concern:

Be it known that I, JOHN S. THURMAN, a citizen of the United States,'residing at St.

Louis, Missouri, have invented a certain new and useful Improvement in Oil-Burners, of

which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make-and-` use the same, reference being had to the accompanying drawings, forming part of this specication, in whichM Figure 1 is a rear elevational view of my improved oil-burner. Fig. 2 is a ver-tical sectional view. Fig. 3 is a plan view of one of the members of my improved burner. Fig. 4 is a' front elevational view. Fig. 5 is a detail View of the centrally-located partitionwall, and Fig. 6 is a detail view of one of the washers.

This invention relates to a new and useful improvement in oil-burners, the object being to construct a burner in a simple and inexpensive manner, which burner will Vbe ecient and economical in the use of fuel and which can be readily taken apart, cleaned, and assembled.

With these objects in view my invention consists in the construction, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In` the drawings, 1 indicates one of the castings of myimproved burner,which forms onehalf of the casing and whose counterpart is represented by the numeral 2, the two castings when assembled with an interposed plate 3 between them forming the completed burner, into which lead pipes 4, 5, and 6, pipe 4 supplying oil or fuel to the burner, pipe 5 supplying compressed air or steam to the burner, and pipe 6 supplying heated air. These pipes have appropriate threaded connections with their respective castings.4

By reference to FigsfZ and 4 it will be seen that the two portions of my improved burner when assembled form an inclosing shell 7, substantially cylindrical in shape and open at one end. Into this cylinderl heated air casting through openings 8.

`width of the opening.

Each casting is provided with a partition-wall 9, forming chambers lOand 1l, chamber 10 receiving fuel and conducting it todischargeopening 12', where it is discharged downsaid plate at its outer edge being beveled so as to direct the issuing oil downwardly,while the air or steam issuing through opening 13 is directed substantially in a horizontal line. By referring to Fig. 4 it will be observedthat the opening 13 is slightly wider than the opening 12,and thisis advantageous,as all the fuel from opening 12 is caught by the blast of air orY steam and carried away from the burner. The plate 3 referred to is preferably cut away at 3' opposite the openings 8, so as to permit the heated air to pass up into the casting 2 and around the chamber I10.

In order to regulate rthe size of theopenings 12 and 13, paper washers 14 and 15 are used on each side of the plate 3, thethickness of each sheet of paper determining the These paper washers are cut awayopposite the openings 3 and 8 and also at the front end of the machine to form the blast-openings.

From the above it will be seen that the 'burner'can be very easily and cheaply made,

as the two castings forming the same are iinished only on their contiguous faces to make a close joint with the Vpaper washers. The plate 3 can be madeof rolled metal and stamped to the proper shape. Securing-bolts are introduced around the marginal Hanges to clamp the two castings together with the plate 3 and its paper washers betweenthem.

While I have mentioned paper as the material of which the washers are composed, it is obvious that sheet metal of different gages can be used, according to the width of the nozzle-openings desired. In fact, paper is referred to on account of its cheapness and ease of renewal.

I am aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be IOO made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oil-burner, the combination with an oil-chamber having a discharge-opening for directing the fuel downwardly, a chamber for containing steam and having a dischargeopening for directing said steam substantiallyin a horizontal direction under the fuelopening, and an air-chamber around said oilchamber and said steam-chamber, the said parts being formed in integral sections adapted to be secured together to form the complete burner; substantially as described.

2. In an oil-burner, the combination with an oil-chamber having a discharge-opening for directing the fuel downwardly, a chamber for containing steam and having a dischargeopening for directing said steam substantially in a horizontal direction under the fuelopening, and an air-chamber around said oilchamber and said steam-chamber and having an uncontracted mouth, the said parts being formed in integral sections adapted to be secured together to form the complete burner; substantially as described.

3. In an oil-burner, the combination with two like castings having marginal anges,said castings havings walls 7 and 9 which form an open-ended cylinder with transversely-disposed nozzle-walls across its open end, a plate interposed between said castings, means for spacing the castings from the plate toform nozzle-openings at the open end of the cylinder, and means for clamping said castings with the interposed plate together; substantially as described.

4. In an oil-burner, the combination with castings 1 and 2,forming a wide open-mouthed air-chamber and inclosed burner of a plate 3 interposed between .said castings, pipes 4, 5 and 6 connected to said castings, U-shaped washers on each side of plate 3 for determining the width of the nozzle-openings, and ymeans for clamping said castings together; substantially as described.

5. In an oil-burner, the combination with castings having walls 7 and 9, a plate 3 interposed between said castings and forming chambers 10 and 11, which chambers have discharge-openings l2 and 13, the latter being the longer and sending its blast in substantially a horizontal direction, and the former sending its blast downwardly so as to be intersected by the blast from opening 13, U- shaped washers on each side of plate 3 for determining the width of said nozzle-openings, means for `securing said castings together, and pipes leading to the several chambers in the castings; substantially as described.

6. In an oil-burner, the combination with two castings, of a plate clamped between them, said plate having a beveled face at one side, a lip on one of the castings coperating with said beveled face to form a nozzle-opening, and washers for forming an adjustable nozzle-opening between the other casting and said plate; substantially as described.

7. In an oil-burner, the combination with two castings, of a plate clamped between them, said plate having a beveled face at one side, a lip on one of the castings cooperating with said beveled face to form a nozzle-opening which directs a blast at an angle to the plate, and washers for forming an adjustable nozzle-opening between the other casting and said plate; substantially as described.

8. In an oil-burner, the combination with two castings, of a plate clamped between them and having a beveled face at one side, a lip on one of the castings cooperating with said beveled face to form a nozzle-opening which directs a blast at an angle to the plate, and means for forming an adjustable nozzleopening between the other casting and said plate, said last-mentioned nozzle-opening directing a blast substantially in the plane of the plate so as to intersect the first-mentioned blast; substantially as described.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 111th day of August, 1902.

JOHN S. THURMAN.
